3 phase digital star delta starter can be used for any application like water transfer or dewatering system. it can be available from 7.5kw to 100kw


3 phase digital star delta starter introduction

3 phase digital star delta starter  PUMP PRO is an Intelligent Pump Controller , easy to use, Control & Protection Device for Direct Start (DOL) or Star Delta Three Phase deep well submersible pump, centrifugal pump, pipeline pump etc with output power from 0.75 KW ~ 75 KW (1HP-100HP)

3 phase digital star delta starter features

3 phase digital star delta starter  PUMP PRO has many operation modes by adopting different electric installations. An important feature that makes the difference between PUMP PRO and common On/Off pump control box is the probe / sensor free in the well. Our special design makes it a very reliable and sensitive protection against pump dry run without installing probe / sensor in the well. PUMP PRO protects Pump against major faults which affect the smooth operation & also increases the life of Pump by displaying Alarms which can be useful for preventive maintenance.

Unique features of 3 phase digital star delta starter

3 phase digital star delta starter  pump pro has 5inch graphics display to easily visualize voltage, current, pump running status, tank water levels etc. It has inbuilt memory of total running hours, and last 20 reasons of tripping.

Application of 3 phase digital star delta starter

3 phase digital star delta starter  can be used for any application like hydro pressure booster system, dewatering system, tank to tank water transfer application, multi tower water transfer application. It can be operated by ss Sensors, float switch, pressure switch and pressure transmitter


1. By-Pass Facility
In case of failure on any electronics part which is difficult to resolve on site, User can by-pass whole electronics circuit by toggle switch and the system will operate directly by pressure switch, pressure transmitter, float switch or any other input signal. Not required to run for emergency service call.

2. Easy detachable control unit / FRC Cable
The controller fitment is done by 4 plastic interlock which is too easy to replace. And all electronics circuit are connected by FRC cable for easy service and replacement

3. Graphical display
3.5 inch Graphics display made this controller more advance & versatile. It shows pump as running, tank water level & pressure switch indication. Display of fault is clearly readable.

4. Inbuilt Memory
All system come with standard 20 fault memory, total pump accumulative running time & last operation pump running hours. It helps in analysis of pump failure.

5. Inbuilt buzzer for fault alarm
In case of any tripping, faulty pump will be shut-off, and system will operate by only working pump. After repairing the pump user can reset in the system
